I am sending your email to the SARA forum so the experts can weigh in.

1) Scope in the box: 
    This system allows you to see the hydrogen line. You can reliably map out the Milky Way with this minimal dish.
     If you tie this with the EZRA software, you can map the galaxy with excellent plots.

     Note: CAS A  and Cyg A are merely directions in the sky. They provide minimal contribution to the hydrogen signal. 

     When you view hydrogen, you are observing the column of space (soda straw) in the direction of observation.

2) Dishes:
     Scope in the box uses a minimal WiFi dish to observe. This appears to be a minimal antenna for observation. After the user views successfully with this antenna, they usually shift to larger diameter antennas and/ or interferometers. Disk yagis are also becoming popular.

Other object observations, such as masers, galaxies, pulsars, etc. require at least a 1 m to 25 m dish.

3) The starter kit for amateur radio astronomy:

    a) IBT - Basic radio astronomy trainer - solar emissions
    b) Supersids - solar flares
    c) Radio Jove - Jupiter emissions
    d) Scope in the Box - hydrogen
    
   The experience with LNAs, receivers and software from these projects provides expertise to observe other objects (frequencies) with larger dishes and different software.


Recommend looking at the YouTube videos for the objects you are interested in. Specifically, Dr. Herrmann's video:

Rich:

Couple quick questions from a double newbie.

  1. What can be observed with the Scope in a Box? In effect, can you detect Cygnus A, Cassiopeia A, etc., or is it only for the Hydrogen Line?
  2. What type of dishes do the people on the video yesterday typically use? Are they special made giant dishes, or what?
  3. Do you have any recommendations of dishes for a beginner who wants to observe objects other than the Sun, i.e. other than what can be seen with the Itty Bitty that I have?

 Thank you.

Hi Rich:

Please let me know you got this.

Thanks for the meeting. Sorry about my abrupt departure, my computer lost power!

I have attached the 10 second video of the IBT.  Show it whenever you want, if you want. 

See you in a couple of weeks.
